1. timer_timeout()
====================

2. select()
==============
    
	sock_fd = socket(AF_INET,SOCK_STREAM,0)

	arg = fcntl(create_socket, F_GETFL, NULL); 
	arg |= O_NONBLOCK; 
	fcntl(sock_fd, F_SETFL, arg);

	ret = connect(sock_fd, (struct sockaddr *)&address, sizeof(address));

	if (ret < 0)
	{ 
		if (errno == EINPROGRESS) 
		{ 
			tv.tv_sec = 1; 
			tv.tv_usec = 0; //1000

			FD_ZERO(&myset); 
			FD_SET(create_socket, &myset); 

			if (select(create_socket+1, NULL, &myset, NULL, &tv) > 0)

				lon = sizeof(int); 
				getsockopt(create_socket, SOL_SOCKET, SO_ERROR, (void*)(&valopt), &lon); 
				if (valopt) 
				{ 
					fprintf(stderr, " SO_ERROR in connection %d - %s\n", valopt, strerror(valopt)); 
					exit(0);
